Abstract
Ultra-long Raman fiber lasers (URFL) have shown great potential in applications including supercontinuum generation, multiwavelength signal processing and quasi-lossless transmission. In this manuscript we focus our attention on the latter, briefly reviewing some of the available tools for the study and numerical optimization of ultra-long laser cavity transmission links reliant upon standard single-mode optical fiber. A typical URFL makes efficient second-order distributed Raman amplification possible from single-wavelength pumps, through the generation of a Stokes wave that is trapped in the transmission link itself by fibre grating reflectors. By adjusting the pump power injected into the active link, it is possible to precisely compensate for attenuation locally all across the transmission length, achieving close-toideal gain distribution and virtual transparency in the fiber. The efficiency with which signal excursion (and ASE noise generation) can be minimised depends on factors such as link length, pump depletion, gratings reflectivity and pumping symmetry. As we will show, numerical simulation can be used to find the optimal cavity design parametres that maximize transmission performance in a variety of circumstances.
